Also, it must be stressed, no DSLR or CCD is going to overcome inadequate guiding. So the beginner must confront the need to buy and use a dedicated guide scope and camera - at extra expense in dollars and learning curve. With a DSLR as an introductory camera, the newbie can afford a QHY5 and an OAG as well as a decent Canon or Nikon as well and for less than the cost of a dedicated CCD. This may sound a bit patronising but with a QHY8/9/10 or some other dedicated CCD, the novice can't use it to take happy snaps of the cat after a night of imaging stars.

Peter,
DSLR's are great, I use them for all my imaging, but the thing is, money isn't really an problem for this guy so thats why I thought he could jump in the deep end with a CCD. I have extra money alloted for the guiding/mount etc. Of course I'll put it to him and see.

It would be worth considering one of the modified cooled DSLR options (I believe jjj uses one with excellent results) from Central DS either the CDS1100 or CDS600D, both are close to your wishlist price.

You haven't mentioned a mount or any other associated hardware, 1200mm F/L is going to need good alignment, tracking and guiding. The newt will also need some sort of corrector (e.g. MPCC) to get decent images.

As the price of a CDS cooled dslr is close to price of a 16 bit cooled QHY8 do you think dslr would be worth it?
As to the mount and guiding, I have ordered an iotron IEQ45 which has GPS to help out with the polar alignment, guiding is something I need to sort yet, know of any good guide cameras that work on a Mac? Something that could double as a planetary camera would be great.
Didn't think about having a corrector on a F6 newt
would it really be that bad?

Will look into a QHY9, just not sure if a mono would be the best for a beginner?

Yes I could do that

If he does not intend to do wide angle imaging, he can get one body only for under $300.

Thanks for the figures Raymo, will certainly put it towards him

And do you use any form of corrector?
Thanks everyone
